Welding Insulation Blanket
Code prefix WIB
Welding insulation blankets are customisable welding auxiliary protection materials that block thermal radiation, reduce heat conduction and reduce heat convection. They are matched to the cooling requirement of the weldment. The main material can be ceramic fiber sintered cloth, ceramic fiber blanket or heat-reflective cloth, and other refractory fiber materials such as bio-soluble fiber can be combined according to the working conditions. Hook-and-loop fasteners, straps and eyelets allow the weldment to be wrapped quickly, and the blanket is made to the outer dimensions of the workpiece.

01 — Product description
Cooling control wrapped around the weldment
Welding insulation blankets are customisable welding auxiliary protection materials with three functions: blocking thermal radiation, reducing heat conduction and reducing heat convection. They are matched to the cooling requirement of the weldment, so the blanket is specified from the welding procedure rather than from a temperature rating alone.
The main material can be ceramic fiber sintered cloth, ceramic fiber blanket or heat-reflective cloth, and other refractory fiber materials such as bio-soluble fiber can be combined according to the working condition. Hook-and-loop fasteners, straps and eyelets allow the weldment to be wrapped quickly, and the blanket is customised and formed to the outer dimensions of the workpiece.
Scope of application
Thermal insulation, temperature control and insulation protection of welding workpieces: the blanket reduces the heat dissipation rate during and after welding, adjusts the cooling rate of the workpiece and reduces the effect of sudden temperature change on workpiece performance.
Working condition suitability and restrictions
Suitable for dry welding operation static insulation protection. Different materials have different temperature resistance, and selection must follow the actual welding temperature; use beyond the material's limit is prohibited. The blanket has no fire extinguishing function and cannot be placed directly over open flames or continuous burning, nor used for long-term liquid immersion, strong acid or alkali corrosion or continuous high-speed airflow erosion.
Usage precautions
- Match the blanket material to the welding temperature, workpiece specification and working condition.
- Ensure the wrapping fits firmly to avoid detachment or displacement.
- Cutting and handling fiber materials release dust; ventilate and wear dust-proof protection.
- Inspect regularly for damage, carbonisation and aging, and replace promptly.
- All technical data are for reference; users should test suitability and follow relevant safety regulations.

Service limits
- Suitable for dry welding operation static insulation; select the material against the actual welding temperature and never exceed its limit.
- No fire extinguishing function: do not place directly over open flames or continuous burning.
- Not for long-term liquid immersion, strong acid or alkali corrosion or continuous high-speed airflow erosion.
- Cutting and handling release fiber dust; ventilate and wear dust protection, and replace the blanket when damaged, carbonised or aged.
